Guest suprawannabe Posted February 23, 2007 Share Posted February 23, 2007 Guys a quick question as been searching but not found anything that helps yet and not 100% sure where to look. Is there any detailed info on here that states roughly what power and torque the gearboxes will take before mods required. After info for the TT and NA for manual 5/6 and auto box options. Also is the autobox different from the NA to the TT. SOrry for the nebie questions but looking at a few options and this info would be reet useful. Cheers in advance.

Sheefa Posted February 23, 2007 Share Posted February 23, 2007 IIRC the Auto box is good for about 450rwhp - TT, and surely the same for N/A but you're not going to get that sort of power from an N/A anyway! No idea on Manual I'm afraid. Link to comment Share on other sites More sharing options...
Supra71GTS_Ice Posted February 23, 2007 Share Posted February 23, 2007 the 6-Speed Getrag will hold almost any power you throw at it. As long as the driver doesn´t mess it up. Just look at Ryan woon he has 1450rwhp and many over 1000rwhp with the 6-Speed Getrag like Cody Phillips, Jon Pratkanis and many others Link to comment Share on other sites More sharing options...
mikeyb10supra Posted February 23, 2007 Share Posted February 23, 2007 IIRC the Auto box is good for about 450rwhp use this as a benchmark, its going to be the torque being put through the components thats going to make it fail in the end!! basically the harder the box works the hotter the transmission fluid gets so cooling is vital if your thinking of using an auto! the w85 manual N/A box I would'nt fancy running higher power on, I would say its russian roulette time if your using it, although some member are and there holding up fine! the 1jz r154 box (5 speed) is slightly stronger and should hold a very mild power upgrade, the getrag 6-speed box is almost invincible if maintained, the clutch being the week link and is the way to go in my opinion!!

fishman Posted February 23, 2007 Share Posted February 23, 2007 I've heard the getrag 6-speed is good for 1000Hp, then again i thought dee ireland was still using this,-but it did eat its self i think?!?! Link to comment Share on other sites More sharing options...

supra666 Posted February 23, 2007 Share Posted February 23, 2007 The Getrag in mine went bang, no joke! and my car was standard!, took me ages to source a new one!, this gearbox is also used in porsche's and BMW's. Toyota quoted me £4985 for a new one. Link to comment Share on other sites More sharing options...
uk-rich Posted February 23, 2007 Share Posted February 23, 2007 The Getrag in mine went bang, no joke! and my car was standard! what caused this, lack of oil ? Link to comment Share on other sites More sharing options...
supra666 Posted February 23, 2007 Share Posted February 23, 2007 what caused this, lack of oil ? No, it had been changed by Toyota 3 months prior to the incident, and judging by the amount of oil that went everywhere it was full, after a good examination, a gear had decided split in two and blew a hole straight through the bottom of the gearbox!, took pictures but can't find them!!

baz78 Posted February 23, 2007 Share Posted February 23, 2007 I run over 1000hp on mine , the getrag 6-speed is a great box . But just like anything else its how heavy your right foot can be :d Link to comment Share on other sites More sharing options...

mikeyb10supra Posted February 23, 2007 Share Posted February 23, 2007 took me ages to source a new one!, this gearbox is also used in porsche's and BMW's. Really?? What models? I never knew this Also where was your new one sourced from?? Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 23, 2007 Share Posted February 23, 2007 Really?? What models? I never knew this Also where was your new one sourced from?? The same FAMILY of Getrag 6 speed is used, but it has different ratios, different bellhousing, different input shaft, different tail shaft and other differences, so it is NOT a swappable item. Whilst a given gearbox MAY hold up under say a torque rise of 20% for a while you can rest assured that it won't like it, wear will increase and it could suffer catastrophic failure. To say that the stock box is "good for" 1000 BHP is patently ludicrous. Link to comment Share on other sites More sharing options...
mikeyb10supra Posted February 23, 2007 Share Posted February 23, 2007 Chris what are your views when it comes to using the getrag on a mild single application on a supra?? surely a smallish single gt35r or similar would not overpower the box? How would you set the car up for the power say for a track car/road + race, not a car being ragged up a drag strip and holding huge burnouts on the clutch every 5 mins?

Chris Wilson Posted February 23, 2007 Share Posted February 23, 2007 It will handle it, but like any transmission, increase the torque or the rpm's and it will wear faster or eventually break. It's a strong box, with a lousy gear shift quality, if I was pushing more torque through one I'd use a different oil in it. But it would be MY box and MY problem if it failed I put near double the torque through a Hewland LD200 transaxle, but i life all the gears religiously, and the CWP, and the life is in terms of about 3 hours running time on the intermediate gears and CWP, and first gear gets changed every 5 race starts. The car should have a much stronger transaxle, but weight was paramount, and the LD is a very light transmission. i have only had one failure, and that was when I had to use a 3 rd gear ratio that should have been binned on its hours run. So, you take a gamble, but used like a Christian, with no race starts, it should handle a small single, with no real risk of total sudden failure, with luck.

JamieP Posted February 24, 2007 Share Posted February 24, 2007 I run over 1000hp on mine , the getrag 6-speed is a great box . But just like anything else its how heavy your right foot can be :d Id love to see if that car makes over a 1000bhp on a uk dyno:) Link to comment Share on other sites More sharing options...
baz78 Posted February 24, 2007 Share Posted February 24, 2007 Id love to see if that car makes over a 1000bhp on a uk dyno:) or a whole load more :) My second car is on the way over to the states as we speak:D Top secret:eyebrows: Link to comment Share on other sites More sharing options...
mikeyb10supra Posted February 24, 2007 Share Posted February 24, 2007 This car is for the drag strip I take it?? Link to comment Share on other sites More sharing options...
baz78 Posted February 24, 2007 Share Posted February 24, 2007 This car is for the drag strip I take it?? Yap :d The yellow one has had NO expenses spared from a full race head to the bottom end . The turbos the intake the motec etc etc etc . If there was something to add i told them to put it on !money was not a issue when you go such lenths. On if it makes a 1000hp ?? well no i does not , it makes a hell more than that:D . And to see it on a uk dyno ?? the speck list tells its own story , It has all the wish list and more. The new car will be just a Drag car Link to comment Share on other sites More sharing options...
Bobbeh Posted February 24, 2007 Share Posted February 24, 2007 Id love to see if that car makes over a 1000bhp on a uk dyno:) Yeah..
